Synopsis
Uncover a reproducible standard of light that underpins modern photometry.
This work explains how researchers moved from fragile flame standards to a solid, temperature-controlled black-body reference, enabling consistent light measurements across labs and time.
The narrative details the search for a dependable reference light, the development of the Waidner-Burgess approach, and the practical steps to realize a reproducible standard. It covers the apparatus, methods, and careful error analysis that make precise photometry possible, including furnace design, platinum interactions, and careful comparisons with carbon standards. The book presents the experimental journey and the measured brightness values that anchor international candle standards.
- How researchers addressed temperature control and surface contamination to improve reproducibility.
- Detailed apparatus and methods for creating a solid reference light from a platinum bath.
- Photometric techniques that compare black-body brightness against carbon standards.
- Careful error budgeting that explains the limits and reliability of the results.
Ideal for readers of historical scientific methods and practitioners seeking a grounded look at photometric standards and their practical realization.

Évaluation du vendeur 4 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book examines the 1908 proposal by Waidner and Burgess for a reproducible standard of light, finally realized through the brightness of a hollow inclosure of fused thorium oxide immersed in freezing platinum. The authors discuss the history of black body standards, the challenges faced by previous researchers, and the significance of their findings. The book delves into the technical details of the experiment, including the apparatus, methods, and results, and explores the implications of the findings for the definition and maintenance of the international standard of light. This book is a valuable resource for researchers and practitioners in photometry, illuminating engineering, and related fields, providing a comprehensive understanding of the development and significance of black body standards in lighting. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
